Are you asking for help to write the FORTRAN code? If so, where are you having trouble?

i have problem with equation . how i should add the equation's to FORTRAN the equation of curve line of airfoil is : Yc= m/p**2(2px-x**2) ===================== from x=0 to x = p Yc= m/(1-p)**2[(1-2p)+2px-x**2] ============ from x=p to x= c Equation for calculate thickness upper and down the middle line of airfoil : + Yt = t/0.2(0.2969 RADICAL x - 0.1260 x - 0.3516 x**2 + 0.2843 x**3 - 0.1015 x**4) - the Equation of final dimensions of upper surface and down surface of airfoil : Xu=x-Yt * SIN TETA Yu=Yc+Yt * COS TETA Xl=x+Xt * SIN TETA Yl=Yc-Yt * COS TETA Where TETA = ARCTAN[dYc/dx] x= chord length y= vertical length t= MAX thickness m= MAX curve p=MAX leading edge curve |

I have a example code but this code is for NACA 4 digit .i need NACA 5 digit also i need the Graphic picture of Airfoil :
i just want Design an Airfoil ..not flow making or analyze . simple 5 digit airfoil design also have graphic form Code: http://people.sc.fsu.edu/~jburkardt/f_src/naca/naca.f90 Last edited by batuning; October 13, 2017 at 07:00. |

i don't have any experience for FORTRAN before im totally new in this if you can make it simple for me .that i can understand and put my numbers to the code , that i exactly want is : only make a 5 digit airfoil and have graphic form of this ( maybe with tecplot or something ... ) i don't need airflow equations ..or any extra thing ...only a design simple airfoil form just it . i also have another better code .but i dont know how to send here |
